Home made SH test?

Guest

Sounds like a good idea to me but I still like the rub test. You can also buy test kits to determine the strength of the bleach. Just google it.

I do the rub test also but I've had some SH in a jug to use for demo's that was a month old and it would still rub hot and turn my fingers white but when I put some on a shingle it didn't work as good as new SH.

Best test is spray on the roof if it cleans it it is the right strength.

I would imagine if you rub it between your fingers, everyone's reaction would be different since we all have different sweat with different salinity, uric acid and all that jazz.

Kits aren't really that much. If you are going to develop jean tests you might as well just buy a real kit.

When the SH arrives on the truck. It is usually 15% It sits in the store after that, and starts to go down in strength. average 12.5%. I dont know the time frame of how it goes down in strength. The finger test? I have some SH, 2 or 3 5'ers, still in the shed. Bought in Nov. Dec? The finger test on them and the new SH? Its not that much different? I remember when we first started washin this way my helper got some on his hand and ran to the hose bib! Too Funnny!!! Reminds me. Got some pics to put up!

How much are the kits, and where do you get them from?

You need to get a high chlorine test kit using DPD. The yellow dye ones are hard to read and carcinogenic!

Maybe something worth stocking lori?

Lori at www.pressurewasherproducts.com posted a link to a kit. It was several months ago if you guys want to try to find it in the search.

Here's one: http://www.amazon.com/Chlorine-Bromine-Pool-Water-Test/dp/B0002IXIIQ

I don't know how good it is. I'd wait for Lori :D

Fresh hot sh will turn a red shop rag grey in less than 1 minute and turn it into shreded bits in less than 1 hour.

I had a pair of old black jeans on yesterday and the front of them are all white specked so that would be a easy test but the test would ruin less clothes ha
